SAN FRANCISCO (AP) — Heat and friction generated while crews were cutting the fuselage of Asiana Flight 214 might be to blame for smoke seen from the wreckage.

KGO-TV cameras captured smoke billowing from the site overnight Friday. The news station says the wreckage began smoking moments after crews used a sling to lift the fuselage.

San Francisco International Airport spokesman Doug Yakel says the fuselage was cut into two pieces to make it easier to transport. He says fire trucks at the scene doused the smoke before it turned into a fire.
